SELECT NEW PARTS

This function enables user to select the new part. The new part will replace the original part as DIE.

 

SHOW NEW

This option is utilized to show/hide the new die.

 

SHOW OLD

This option is utilized to show/hide the original die.

 

POSITION NEW PARTS

The positioning between the new and original parts is very important to ensure good result. Due to similarity between the new and original parts, the user can use three different methods to position the new part:

l 3 Point Absolute

Three reference points are selected on the new die parts and original die parts. The first selected reference point on new die is used to position the new die parts. The other two reference points are used to orient the new die part. Three arrows are plotted on screen after the reference points are selected. An illustration is shown in Figure 6.4.7.

 

NOTE: The distance between the selected three points should large enough to ensure good positioning result.

Figure 6.4.7  Three Points Absolute

 

l 3 Point Plane

The average of the three selected points (the center point of three points) is used new die parts. The center point of selected point on new die parts is moved to the center point of selected three points on old die part accurately after positioning. The other two points are used to orient the new die part. Three arrows are plotted on screen after the points are selected.

 

l LCSàLCS

This method is used to position the new die parts through defining LCS on new and original die parts. The LCS on new die parts is matched with the LSC on original die parts to position the new and original die parts.

 

UNDO

Undo the last position operation.

 

APPLY

This function enables user update the addendum of new die parts. An illustration of updated addendum is shown in Figure 6.4.8.

Due to minor differences between the new and original die part, some gaps or overlap elements may exist between the original addendum and the new die part. The user may need to adjust some points on original addendum to the new die parts. After the function is selected, some arrows are displayed from point on original addendum to the new die part. The user has to adjust the corresponding point by selecting the head of an arrow. Then, the user can select a new position on screen to change the corresponding point. Figure 6.4.8 illustrates the position of corresponding points.

After the adjustment is completed, the user can click on middle mouse button to update the addendum on new die parts.
